EasyQRScan: Compose Multiplatform QR-Code Scanner
QR-Code (or other 2D/3D-Codes, see below) Scanner for Compose Multiplatform (Android/iOS). Currently, the implementation is rather rudimentary.
Supported Compose version:
| Compose version | EasyQRScan Version |
|---|---|
| 1.6.x |
Dependency
Add the dependency to your commonMain sourceSet (KMP) / Android dependencies (android only):
implementation("io.github.kalinjul.easyqrscan:scanner:0.7.0")
Or, for your libs.versions.toml:
[versions]
easyqrscan = "0.7.0"
[libraries]
easyqrscan = { module = "io.github.kalinjul.easyqrscan:scanner", version.ref = "easyqrscan" }
Setup Camera Permissions
Include this at root level in your AndroidManifest.xml:
<uses-feature android:name="android.hardware.camera"/>
<uses-feature android:name="android.hardware.camera.autofocus"/>
<uses-permission android:name="android.permission.CAMERA"/>
Add this key to the Info.plist in your xcode project:
NSCameraUsageDescription and provide a description as value
Usage
The scanner is included by calling a single composable function Scanner() or ScannerWithPermissions:
// basic permission handling included:
ScannerWithPermissions(
onScanned = { println(it); true }, // return true to disable the scanner, false to continue scanning
types = listOf(CodeType.QR),
cameraPosition = CameraPosition.BACK,
enableTorch = false // toggle this to enable/disable the flashlight
)
// or, if you handle permissions yourself:
Scanner(onScanned = { println(it); true }, types = listOf(CodeType.QR))
Check out the sample app included in the repository.
